GeForce 8600 GT 512MB DDR2 vs GeForce GTX 965M

Intro

The GeForce 8600 GT 512MB DDR2 features core speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare those specifications to the GeForce GTX 965M, which comes with a core clock frequency of 944 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2 47 Watts
GeForce GTX 965M 60 Watts
Difference: 13 Watts (28%)

Memory Bandwidth

In theory, the GeForce GTX 965M will be 400% faster than the GeForce 8600 GT 512MB DDR2 in general, due to its higher data rate. (explain)

GeForce GTX 965M 64000 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 51200 (400%)

Texel Rate

The GeForce GTX 965M will be quite a bit (approximately 599%) faster with regards to texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce GTX 965M 60416 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 51776 (599%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 965M is a better choice, and very much so. (explain)

GeForce GTX 965M 30208 Mpixels/sec
GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Difference: 25888 (599%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
